A highly reactive magnesium oxide intended specifically for use in the rubber processing industry; improves the processing safety of CR, CSM, CM and CIIR based rubber compounds by increasing the critical temperature of basic accelerators; reduces the susceptibility of rubber compounds to scorching; In acid accelerators, it lowers the necessary activation temperature; in polymers containing halogen, and particularly in CR, it acts as an acid acceptor, thereby improving aging properties; in cold-cured fabric proofing, it serves to neutralize traces of acid; moduli are generally increased by Rhenofit D/A.

An active magnesium oxide especially selected for the use in the rubber processing industry; improves the processing safety of rubber compounds based on CR, CSM, CM and CIIR; raises the critical temperature of basic accelerators and thus prevents scorching; In acid accelerators, the activiting temperature of acid accelerators is decreased; in polymers containing chlorine, especially CR, it serves as an acid acceptor and thus improves the aging properties of the vulcanizates; in cold cured rubber coated fabrics, Rhenofit 2120 is used to neutralize acid traces; moduli are generally increased by its addition.

Curing activator and acid acceptor particularly suitable for polychloroprene rubber (CR) and adhesives. a low active magnesium oxide especially selected for the use in the rubber processing industry; improves the processing safety of rubber compounds based on CR, CSM, CM and CIIR; raises the critical temperature of basic accelerators and thus prevents scorching; for acid accelerators the activating temperature is decreased; in polymers containing chlorine, especially CR, it serves as an acidacceptor and thus improves the ageing properties of the vulcanizates; in cold cured rubber coated fabrics, it is used to neutralize acid traces; moduli are generally increased by the addition of Rhenofit 2060.

Preferably used as an activator in acid resistant compounds. It considerably reduces the swelling of vulcanizates in water; is suitable as an oxidizing agent for the vulcanization of butyl rubber with p-quinone dioxime; can be used to improve the heat resistance in peroxide cured CPE compounds; is not recommended for use in thiadiazole cured CPE; filler in compounds for protective covering, because of the high absorption capacity to x-rays.
